My Alpine V12 is shutting down after it's been on for a while. And then it comes back on intermittingly at times. Any ideas?
is it in an area that has no ventilation, making it get hot quickly?
yeah, that bitch was real hot when I got home just now...I was just looking into wiring a fan on top of it some how...
00galantman, your sig is the best, lmao
Yeah, I stole it from another forum somewhere. :lol: But I like it...Quote:

I like that idea, I'm going to try that. The guy at the Dr. Dashboard here said that I'm working the amp too hard, because I have two speakers bridged to one channel. But I've done it before with no problem. I'm going to re-wire it and see what happens...Quote:

They are made to be bridged, however if the total resistance of the subs is below what the amp can handle when bridged you will have problems like thermal shutdown or possible damage to the amp. Most 2 channel amps are only stable at 4 ohms when bridged mono.Quote:

Here's the specs on the amp...
RMS Power (at 12V, 20-20kHz)
Per Channel into 4ohms .... 50W x 2 (0.08% THD)
Per Channel into 2ohms .... 100W x2 (0.3% THD)
Bridged 1 Channel into 4ohms ....200W x 1 (0.3% THD)
Dynamic Power (at 14.4V, 20-20kHz)
Per Channel into 4ohms ....75W x 2 rms (0.08% THD)
Per Channel into 2ohms ....150W x 2 rms (0.3% THD)
Bridged 1 Channel into 4ohms ....300W x 1 rms (0.3% THD)
What kind of speakers would I need to get so that I can can bridge the 2 12's into one channel?
I currently have 2 RF punch2's I can't find any specs on them though...
u wanna get two dual 4ohm subs and wire like this

I really liked the sound of the way I had it wired bridged like that. My trunk lid looked like it was going to jump off the car it was hitting so hard. It was actually bowing the sheetmetal of the trunk out :lol: And it worked fine for a little while, but after about 30 minutes of listening time, that's when it started to act up. :( But my RF's are only single voice coils, not duals like shown above...
do u know if they are single 2 or single 4?
No idea. I can't find the specs on them...prolly 4Quote:

I like the title: Stupid Amp!
move the amp to a better area, try turning the settings down also for the time being, see if that helps at all

i think you might be straining the amp to try and push them subs. it's finally just taken it's toll on the amp. try adding the washers and moving it to a place with alot of air flow.
that's nothing .. try blowing all the welds on the skeletal part of the trunk lid :wink: Like said before the amp might be struggling to push those subs...Quote:

Can you take a closer pic of the dust cap. They look like they might be he2's or possiblly hx2. Best bet though would be to pull one out and look on the back of it. The model info will be printed on a sticker on the magnet.
i have the HX2 and it is a 4 ohmQuote:

Mine just say Punch2 on it...
When they were availible you could get either as a dual 2 ohm. A lot harder to find though.Quote:

Then what could be happening is your stretching the speakers out so far that the coil bottoms out and it causes a short in the speaker, just for a split second. And if that happens enough times in a row it causes the amp to over heat and shut it down. Your problem sounds like one i had when i first started hooking up subs in my car. I thought maxing out the speakers was the route to go, but it actually isnt. What you want is some powerful subs and a weaker amp.
